A multi-step method is disclosed for exchanging heat in a vapor compression heat transfer system having a working fluid circulating therethrough. The method includes the step of circulating a working fluid comprising a fluoroolefin to an inlet of a first tube of an internal heat exchanger, through the internal heat exchanger and to an outlet thereof. Also disclosed are vapor compression heat transfer systems for exchanging heat. The systems include an evaporator, a compressor, a dual-row condenser and an intermediate heat exchanger having a first tube and a second tube. A disclosed system involves a dual-row condenser connected to the first and second intermediate heat exchanger tubes. Another disclosed system involves a dual-row evaporator connected to the first and second intermediate heat exchanger tubes.

A method of recovering energy produced by the change of phase of dry ice using a device having an enclosure () containing dry ice at an infra-atmospheric pressure and at a solidification temperature corresponding to the infra-atmospheric pressure; and a primary energy recovery circuit (), in which a heat transfer fluid circulates, passing through the enclosure. The method involves passage of the heat transfer fluid into the primary circuit (), this step causing the heating of the dry ice and its change of phase into CO2 and the cooling of the heat transfer fluid; extraction of the CO2 contained in the enclosure (); and substantially continuous lowering of the pressure of the enclosure () to an infra-atmospheric pressure.

The invention relates to a method of cooling a metal strip traveling through a cooling section in a continuous heat treatment line. In accordance with the invention, the method consists in projecting a refrigerant medium into the cooling section () onto the surface of the strip () to be cooled, the medium being constituted for the most part by a phase-change substance that passes into the gaseous phase at a temperature that is lower than the temperature of the strip () and without oxidizing said strip so that energy is exchanged within an endothermic process by a change in the phase of said phase-change substance.

The present invention relates to a method and a system for controlling the circulation of water films on the exchange walls of an exchange surface of a cooling tower. It comprises combining a tank and a dispenser lip to ensure that the film has a specific thickness and that it adheres to the exchange wall right from the moment it starts to flow and repeatedly so, on each exchange wall. The exchange walls between air and water are horizontally sloping at a small angle, thereby ensuring that the water flows by force of gravity and, at the same time, limiting the speed increase on the plate to avoid the droplets from being pulled away by the airflow. The water films are recovered in recovery troughs perpendicular to the flow of the water films on the plates. These troughs are tilted horizontally, and enable the recovery of the water films without being crossed by the air flows. The air is blown in by nozzles which are interposed between the water flow plates in such a way that the airflow is in a counter-current flow or, if necessary, in a cross-current flow, relative to the water films thus enabling the evaporation of the water that cools the water flow on the exchange plates without forming liquid aerosols.

The present invention pertains to a method and an installation or system for drying fibrous material. The method comprises the step of ventilating very moist air through the fibrous material located in a drying zone. The moisture content of the moist air is less than that inside the drying zone, its pressure is close to atmospheric pressure and its temperature is higher than that of the material to be dried. The method additionally comprises the step of recovering the heat of condensation of the water vapor extracted from the fibrous material to heat the moist air, providing leaks between the outside ambient air and the ventilation circuit upstream and downstream of the drying zone, making possible a mass and heat exchange. It is possible to ensure heat and mass balance without expelling large amounts of moist air into the ambient air.
